Will,

Not sure if you ever got this working.  I got busy and didn't reply 
before.  See my comments below.

I'm assuming that you have full control over that Win2k3 box right? 
Direct whatever app is sending the mail to use your hylafax/postfix box 
as the mail server.  That way, if you send mail through the hylafax box 
(with postfix installed and configured properly), postfix should see 
that it is handling mail for that domain and not ever look at the DNS.

Ok.  Here's what you do.  Tell the Windows webserver to use the Postfix 
box as the mail server.  Have postfix handle fax.yourdomain.org locally 
by postfix, then relay all remaining mail to the existing Windows 
server.  (look for "relayhost" in the main.cf file)

Hopefully that all makes sense.
